Definitions

  • Certain organizations dispatch large amounts of mail on a periodic basis. Examples of such organizations are: banking institutions, utility companies, insurance companies, credit companies, and the like. With such large quantities, these mail senders normally pre-package and pre-sort their mail and are given a lower postage rate by the postal service because of the time saved by the postal service. There are generally two ways in which such mail senders apply postage to their mail. The most common way is by use of a postage meter which is leased by the mail sender from a postage meter manufacturer with which the amount of postage required is applied to each mail piece. Inserter systems have been developed whereby inserts may be place into an envelope, the envelope may be sealed, addressed and have a postage indicia applied thereto.
  • the mail pieces may be weighed on the fly or individual weighing may not be required if all the mail pieces are of like kind, i.e., only a sample mail piece need be weighed. Additionally, the weight can be calculated based upon a knowledge of the inserts to be processed. These acts of processing mail may be performed at a relatively high rate of speed.
  • a second method of mailing large quantities of mail pieces is the permit mail system.
  • the mail sender places a permit number on the mail pieces and prepares a manifest listing that shows the type and number of mail pieces being mailed on each occasion and the postage required. All the mail pieces are generally of the same type and weight.
  • the postage meter In the case of the postage meter, the lessor of the postage meter, i.e., the postage meter manufacturer, is required by law to inspect the postage meter at least twice a year to ensure that there is no evidence of tampering with the postage meter that will indicate an attempt to obtain unauthorized postage.
  • permit mail large quantities of the same type of mail will be mailed at one time and the postal service will conduct an inspection to verify that the manifest listing accompanying the permit mail accurately accounts for the amount of postage due for the mail that has been processed by the postal service. This is accomplished through an inspection on the part of the postal service by examining the records of the mail sender on every occasion.
  • a system has been conceived whereby a mail sender will be able to send large quantities or batches of mail without the need of on-site inspections. This is accomplished by the mail sender having a secure accounting unit similar to a postage meter in which postage value is placed by a dispensing or central station.
  • a statement accompanies each batch of mail which statement may include information relative to the mail and the amount of postage required to send the mail and the amount of postage value remaining with the mail sender.
  • Communication between the central station and the mail sender allows postage value to be transferred to and from the mail sender by the central station and mailing and verification data to be sent to the central station from the mail sender.
  • the mailing and verification data will be the same as that contained on the mailing statements that accompany the batches of mail.
  • This system provides a central station for a large number of mail senders whereby the postal service is relieved of its obligation of having on-site inspections and the central station acts as a clearing house for the postal service through whom verification of postage can be conveniently and
  • a scheme has been devised whereby tampering with the accounting unit may be detected.
  • the accounting unit is provided with a sensor, or sensors, that detect any tampering or attempt to tamper.
  • the sensor will communicate this detection to a processor that will control the bar code printer that prints the zip code in bar code form on a mail piece.
  • the bar code will be altered so as not to conform to postal regulations.
  • the mail with invalid bar codes will be placed in a reject bin and the discovery of tampering would occur.
  • a feature of this invention is that security for a postage meter or accounting unit is provided while allowing a high speed, relatively inexpensive printer to be used for printing mail and postage information.
  • Another feature of the present invention is that a scheme for discovering tampering upon a postage meter or accounting unit is provided that needs no change in post office equipment.
  • Yet another feature of the present invention is the provision of a postage meter like device with enhanced security capability to enable the generation of bar codes that can be altered to evidence tampering with accounting equipment.
  • Still another feature of the invention is that security of an accountng register in a postage meter like device can be provided.
  • a further feature of the invention is that the evidencing of tampering is not apparent to the wrongdoer.
  • Another feature of this invention is the automatic prevention of the postal service from expending time and money processing, transporting and delivering mail produced from an accounting unit or postage meter upon which tampering has taken place.
  • FIG. 1 is a block diagram of a batch mailing system with tampering detection features
  • FIG. 2 is a plan view of an accounting statement that would accompany batch mail sent by the system of FIG. 1.;
  • FIG. 3A is a plan view of an envelope containing information that would be applied thereto by the system of FIG. 1;
  • FIG. 3B is the bar code portion of the envelope shown in FIG. 3A.
  • FIGS. 4-6 contain flow diagrams that describe the functions of the system shown in FIG. 1.
  • a batch mailing system is shown generally at 10 and includes a post office 12, a data center or central station 14 and a user location 16.
  • the central station 14 has a processor 18.
  • This processor 18 could be a main frame type of computer having substantial capacity.
  • Communication is provided between the post office 12 and a plurality of central stations 14 (only one being shown) through a line or communication link 19 having a communication device such as a telephone type system 20 therein.
  • a large storage memory unit 22 where large amounts of data can be stored and a register setting device 23 which includes encryption software of the type required in the resetting of postage meters remotely.
  • Systems for the resetting of meters remotely are well known, see for example U.S. Pat. Nos. 3,792,446, 4,097,923 and 4,447,890.
  • a remote user location 16 has a secure accounting unit 25 which will hereafter be referred to as a "server".
  • the server 25 is supplied by the central station 14 to the user and includes a user processor 24 which may be a processor of much smaller capacity such as an Intel 8085 processor available from Intel Corporation, Santa Clara, Calif.
  • a memory 26 Connected to the processor 24 is a memory 26.
  • the memory 26 will be a non-volatile memory (NVM).
  • the user processor 24 is connected to the central station processor 18 through a communication link or line 28.
  • a telephone type system 30 or other communicating device may be disposed within the line 28 to thereby provide selective communication between the processors 18, 24.
  • a RAM 32 Also connected to the processor 24 are a RAM 32, a ROM 34, an encryptor 35, a clock 36 and a sensor 37 whose respective functions will be described in detail hereinafter.
  • An input/processor 38 is connected to the user processor 24 whereby data may be supplied, either manually or through a medium such as a coded paper, disc or tape, to the user processor 24 for the purpose of providing data required in the processing of mail pieces.
  • the server 25 has many characteristics of a postage meter as well as differences that will be discussed hereinafter. Although the invention is described as it applies to a server 25 specifically, it will be appreciated that the principles of the instant invention are applicable to postage meters having variable printing capability as well.
  • Postage meters are mass produced devices for printing a defined unit value for governmental or private carrier delivery of parcels and envelopes.
  • the term postage meter also includes other like devices which provide unit value printing such as tax stamp meters.
  • Postage meters include internal accounting devices which account for postage value representation which is stored within the meter. The accounting device accounts for both the recharging of the meter with additional postage value and the printing of postage by the meter printing mechanism. Accordingly, postage meters must possess high reliability to avoid the loss of user or governmental funds stored within the meter and dispensed by printing postage.
  • a high speed inserter 39 is in electrical communication with the server 25 and performs the physical acts involved in processing the mail such as the inserting of inserts into envelopes, sealing the envelope flaps, orienting the mail pieces and conveying the mail pieces to a postage meter or printer.
  • the term "insert" includes bills, advertising materials, notices, etc., which are of a size to be received within an envelope or the like.
  • High speed inserters of this type are readily available commercially, as for example Inserter model No. 3100 series from Pitney Bowes Inc., Stamford, Ct.
  • a first printer 40 is in communication with the user processor 24 of the server 25 and with the input/processor 38 and is able to print upon mail pieces 42 such as envelopes containing inserts which it receives from the inserter 39.
  • This printer 40 is one provided by the user and will be an unsecured, high speed printer which may be controlled either through the processor 24 or input/processor 38.
  • a second printer 44 is provided to print upon a statement sheet 46 or other document.
  • This second printer 44 is preferably a secure printer that is provided by the central station 14. Obviously, the second printer 44 can be an unsecured printer but this occasions greater risk in terms of verifying payment of postage.
  • this statement sheet 46 will be referred to as a "passport". Details of the passport 46 will be described hereinafter in conjunction with FIG. 2.
  • the central station 14 may be the location of a postage meter manufacturer or other accountable organization.
  • the user of the user location 16 will be given a identification number by the central station 14 that will be placed in the NVM 26 of the server 25.
  • This identification number will be permanent and unique for each server 25 and the user will have no access to that portion of the NVM 26 that stores the identification number. It will be appreciated that this feature may be applied to postage meters as well. Having the identification number in memory 26 eliminates the need of having a plate applied to a postage meter or a server 25.
  • a server 25 has many characteristics of a postage meter, i.e., security, a descending register and the like, but certain elements are absent. The most evident absent element is a printer, the advantage of which is described throughout. Another absent member is an ascending register.
  • an ascending register is accessible only by a service representative of the meter manufacturer and may be used to determine if any meter tampering has taken place.
  • the user will communicate with the central station 14 through the telephone 30 for the purpose of indicating to the central station 14 the amount of postage value it wishes to have accredited to its memory 26.
  • An access code will be given to the user that is addressed to the setting device 23 through the touch dial of the telephone 30. Upon the receipt of the access code, the user will transmit to the central station 14 the proper code and identification number.
  • the setting device 23 will function to supply, or increase, the postage value in the memory 26.
  • This memory 26 will include a descending register which is charged by the central station 14 with the selected amount of postage value. As the user location 16 processes mail, the postage value in the descending register will be decreased in accordance with the postage required to process the mail pieces.
  • the amount of postage value applied to the memory 26 may be recharged automatically. For example, when the descending register attains a certain minimum postage value, a message is sent from the memory 26 to the processor 24. Upon receipt of the message, the processor 24 will automatically cause communication through line 28 with the central station 14 and request that additional postage value be charged to the descending register of the NVM 26. This would be carried out by the processor 18 in combination with the setting device 23.
  • the balance of the server 25 includes the ROM 34 that contains a series of programs for controlling the functions of the server 25, a RAM 32 that will hold and supply real time data, a clock 36 that will provide the time and date, an encryptor 35 that will generate the code required for the descending register setting functions and a sensor 37 that will detect tampering with the server 25.
  • the encryptor 35 can be any one of a number of encrypting devices including devices which use the Data Encryption Standards described in FIPS P4B 46, dated Jan. 15, 1977 and published by the U.S. Department of Commerce, National Bureau of Standards.
  • the printer 40 is a high speed, unsecured printer such as a ink jet printer or laser printer which will apply the addresses of the addressees including the zip code in bar code form 47, and addressor to the face of the mail pieces under command of the input/processor 38.
  • other information can be printed by the printer 40 upon each mail piece 42 when under command of the processor 24.
  • This information includes a transaction number (T.A. No.), the run of the particular batch of mail, the date and time of mailing, the class of mail and a batch number.
  • the transaction number is that number assigned to the user location 16 by the central station 14 everytime postage value is added to the server 25 and will be stored in the NVM 26.
  • This transaction number will be the same for one or more batches of mail that are sent and will remain until such time as the descending register of the NVM 26 is recharged with postage value, at which time a new transaction number will be assigned and stored in the NVM in place of the preceding transaction number.
  • the batch number is one assigned by the user through the input/processor 38 whereby a given batch of mail, i.e., mail of a particular type or character, will be identified by a number assigned by the user.
  • a run number which is a subset of the batch, may be given to identified particular segments of the batch.
  • the user When a batch of mail is to be sent, the user will supply mailing and verification information through the input/processor 38 into the user processor 24 which will transmit at least a portion of this information to the inserter 39.
  • This information would include the number of mail pieces to be processed and number of inserts to be placed in each envelope 42.
  • the time and date may be supplied to the printer 40 through the input/processor 38 by overriding the clocks 36. This is useful when future mail is being processed.
  • the user processor 24 will then command the printer 40 to print the appropriate postage, time, date, transaction number, address on the mail pieces, and a zip code in bar code form 47 for a particular run. This run will be given a number that is associated with the particular mail to be sent, which number will be printed on the envelopes 42 of that run.
  • the printer prints the appropriate information upon each mail piece, the number of mail pieces and amount of postage required will be determined by the processor 24.
  • the second printer 44 At the end of the run or batch, the second printer 44 will print required information upon
  • the passport 46 is shown after having printed thereon the total postage (Post. Total) required to mail the batch of mail, the transaction number, piece count for a batch, descending register amount (Reg. Am.) after subtraction for the postage, the date, the time, the class, the batch number and the run. Additionally, the name of the server number identification number stored in the NVM 26, user name and any desired graphics can be printed.
  • This information on the passport 46 serves many purposes.
  • the register amount acts as a physical record of the postage value stored in the descending register of the NVM 26. This amount is printed on the passport 46 on the upper right hand. The register amount will be that amount in the descending register after all postal charges have been made for the batch of mail to be sent.
  • the server 25, as well as postage meters in general can be conditioned to print the value of the descending register, and any other data of interest such as the date and time of the day, after each imprint is generated.
  • the present concept of printing the descending register value and other information of significance can be incorporated in servers 25 or postage meters without the use of other aspects of the present invention.
  • the transaction number provides an authorization check as does the identification or server number. By changing the transaction number with each recharge of the server, one can readily determine if more postage accompanies a transaction number than is authorized.
  • Also printed on the passport 46 will be the date and time the passport 46 is printed, the piece count, i.e., the number of mail pieces mailed in the particular batch, and the class of mail. Upon the printing of the information on the passport 46, the postage amount for the batch will be subtracted from the descending register in the NVM 26.
  • the information printed upon the passport 46 is transmitted to the central station 14 through the communication line 28 automatically after each batch, is processed so that a record is maintained through the processor 18 that communicates with memory 22.
  • the memory 22 has an ascending register therein that corresponds to the descending register in the server 25, i.e., one is the inverse of the other. As is known, an ascending register is one that accumulates charges over a long term.
  • the memory 22 may have a descending register that duplicates the amounts in the descending register in the NVM 26 on an ongoing basis.
  • the total amount credited to the user location 16 will be stored in memory 22 and if the amount in the ascending register exceeds that total amount the user location 16 will be notified that there are insufficient funds.
  • the passport 46 for that particular batch will accompany the mail.
  • the postal employee can determine whether it is an authorized transmission of mail from the information contained upon the accompanying passport 46. If there is any question of the part of the postal service as to whether the information is authentic, it will contact the central station 14 and through the line 19 obtain the information from the central station 14 to verify the information contained on the passport 46. If this information is accurate, then the postal service will know that the mail is authorized, i.e., the postage for the mail has been paid.

Envelopes 42 are occasionally placed in the reject bin, but when tampering is evident, all the mail pieces of the batch would be diverted to the reject bin and the postal clerk would be alerted that the user's server 25 has experienced tampering and would act upon this by notifying the appropriate authorities. The authorities then would visit the user location 16 and inspect the server 25 for evidence of tampering.
